***OFFICIAL AP Physics C Thread 2013***

<h1>2 part d is literally an AP Calc problem, which I think is stupid. Test on the physics, not the math.</h1>

<p>Those answers look right @FastNeutrino. I also think part d is stupid, considering I’m not taking calculus or any math at all this year so I’m really rusty. I completely forgot to separate the variables (I put dt and dv on opposite sides of where they should have been). Hopefully it doesn’t make a difference in my score…</p>

<p>Thanks for #2!</p>

<p>Can Someone Please do# 3 On the Mech?</p>

<p>ATTENTION ANYBODY WHO HAD FORM E:
What did you guys estimate for the linear acceleration in Mechanics Question 3? Did you guys get around 27?</p>

<p>So I’m pretty sure I only got like half credit on the 3rd open ended but still have a good shot at a 5 since I did really well on the first two. I just need like 15/35 on the MC, which even with a few guesses I’m pretty sure I have a good shot at.
This is exciting. =P
@Nutmeg: No problem! Thank god I didn’t submit my #3 to the forum though… it’d have to get torn apart. =P</p>

<p>Which form was released? The O one?
I got a different set totally.</p>

<p>Is it true that the mark for a 5 has gone up from 53 to 60 because of the fact that penalty has been removed ??</p>

<p>No, if you take a look at the scoring worksheet here for Physics B and C: <a href=“Supporting Students from Day One to Exam Day – AP Central | College Board”>Supporting Students from Day One to Exam Day – AP Central | College Board;

<p>On the top, you can see that the College Board has already changed the scoring guidelines to be accurate with the removal of the guessing penalty.</p>

<p>The problem is that I heard the AP Chem boundary went up from 100 to 110 for a 5, so I’m assuming something similar may happen to the AP Phys</p>

<p>I probably got a 3-4 on Mechanics and a 2 on E&M. Mechanics was okay, I guess, but E&M was like nothing we’d ever done in class. I can’t even bring myself to look at those sample responses.</p>

<p>Guys, if I miscalculate the time on the multiple choice part and basically just guess Cs in last 10 in AP electricity, is there any possibility to get a five…so sad…</p>

<p>Does anybody have solutions to the mechanics free response (or the E&M, for those who took it)?</p>

<p>I’m taking the late exam tomorrow. Any tips?</p>

<p>i took the late exam, pretty sure i nailed the 3rd question involving calc
(take the derivative of sqrt[(1/12*ml^2+mx^2)/mgx]</p>

<p>Hey!
I made this page and I guess I will be the first to post my AP Physics C scores!</p>

<p>Predicted:
Mechanics - 4
E&M - 2</p>

<p>Actual:
Mechanics - 5
E&M - 2</p>

<p>On my Mechanics exam I only answered 20 of the 35 multiple choice and I only answered half of the free response section!
For electro I self studied but only studied the electro part, not any magnetism.</p>

<p>Yay for AP Scores!</p>

How did you get your AP score so early???</p>

<p>Some people have their ap scores updated on their college portal.</p>

<p>How did all my East Coast friends do?</p>

<p>west coast here (shhh)</p>

<p>5 on mech and 4 on e&m</p>

<p>I expected to do pretty well on mech, but the curve on e&m must have been suuuuuuuuuuper nice</p>

<p>I only answered the last frq and not even all of it and i basically left the first two blank, and i thought the multiple choice was much tougher than the ones i took in practice, so i really had no hope for e&m, thought i got a 2 or 3. So happy right now.</p>
